The origin story of the Gumazing Gum Girl! Dun! Dun! Dun!

The story fell a little short for me and I didn't like the way the class bully was portrayed BUT the art is adorable, the main character is a gum-loving bilingual Latina (of Mexican heritage I think) who peppers a little Spanish into her speech, the adventure is fast-paced and entertainingly ridiculous (like Captain Underpants but thankfully with less underpantastic humor), and the book cover literally smells like bubble gum. I cheated and looked ahead in the series, and I think this one definitely works better for me when taken as part of the whole series.

Content notes: breaking rules, disobeying parents and hiding things from them even when it burgers her conscience to do so, class bully depicted as a large masculine girl
